What kind of food does Loach eat?

Loach often come out at night to prey on plankton, aquatic insects, crustaceans, aquatic higher plant detritus and algae, and sometimes take water bottom humus or mud residue. During artificial culture, the kinds of bait fed are fly maggots, fish meal, pig blood meal, silkworm pupa meal, rice bran, wheat bran, vegetable cake and so on.

The living habits of Loach

1. Habitat: Misgurnus anguillicaudatus likes to inhabit the bottom of still water and often haunts the silt surface rich in plant debris at the bottom of lakes, ponds, ditches and paddy fields, and is highly adaptable to the environment. The living water temperature is 10-30 ℃, and the optimum water temperature is 25-27 ℃, so it should be a warm-water fish. When the water temperature rises to 30 ℃, Loach will dive into the mud to spend the summer. When the water temperature drops below 5 ℃ in winter, it is drilled into the mud at a depth of 20 to 30 centimeters to survive the winter.

2. Reproduction: Misgurnus anguillicaudatus matures at the age of 2 winter and begins to reproduce in April every year (water temperature 18 ℃). Eggs are laid in shallow grass with a water depth of less than 30 cm, and the eggs are attached to water plants or submerged dry grasses. Hatched larvae are often scattered and do not form groups.

3. Breathing: Misgurnus anguillicaudatus can not only breathe with Gill and skin, but also has special intestinal respiratory function. When the gas is muggy or the pond bottom silt, humus and other substances rot, causing serious hypoxia, the Loach can also jump out of the water surface, or rise vertically to the water surface, swallow the air directly with the mouth, and breathe with the assistance of the intestinal wall. When it turns its head and slowly dives, the exhaust gas is discharged from the anus. Cold in winter, the water body dries up, the Loach drills into the soil, relies on a small amount of moisture to keep the skin from drying, and relies entirely on intestinal breathing to sustain life.

Variety classification of Loach

1. Misgurnus anguillicaudatus: Misgurnus anguillicaudatus is commonly known as Loach, with a long cylindrical body, flattened tail, lower mouth and horseshoe shape. 5 pairs of moustache, 3 pairs of maxilla, larger, 2 pairs of mandible, one big and one small. The caudal fin is round, the scales are small and buried under the skin. The back and back of the body are grayish black with small black spots. The lower part of the body is white or light yellow, and there is a large black spot above the base of the caudal stalk. There is more mucus on the body surface, the head is pointed, the snout protrudes forward, and the eyes and mouth are smaller.

2. Misgurnus anguillicaudatus: Misgurnus anguillicaudatus is distributed in the middle and lower reaches of the Yangtze River and its accessory water. The body is very similar to Loach. Must be 5 pairs. The eyes are covered with a membrane. No thorns under the eye. The scales are large and buried under the skin. The skin of the caudal stalk is well-developed and is connected to the caudal fin. The length of the tail handle is about equal to the height. The caudal fin is round. The anus is near the starting point of the anal fin.

3. Misgurnus anguillicaudatus: Misgurnus anguillicaudatus is distributed in the middle and upper reaches of the Yangtze River. Also known as Loach. The kiss is long and sharp. Must be 3 pairs. The lower part has a pair of button-like protuberances. The thorn bifurcates at the moment, and the end exceeds the posterior edge of the eye. Cheeks are scaleless. The anus is close to the starting point of the anal fin. The tail handle is low. Living in the slow water area of the sand and gravel bottom reach, often living in the bottom layer.
